I personally do not like Glocks, or more accurately, they don't seem to like me and I've owned two and fought like mad to not be issued a third. I would go with an S&W or Colt snubbie myself. These are pretty much foolproof and require much less care, cleaning, and familiarity to use proficiently. There are many other brands of semi-autos out there that might be a better choice for you and you should find a range with rental guns to "test drive" them yourself. For concealed carry I lug around either a compact 1911 model or lately a Kel-Tec in 40 S&W. The Kel-Tec is a fairly cheap gun but seems to be pretty reliable in the .380 ACP, 9mm, and 40 S&W. My P-40 has over a couple thousand rounds through it between me and the previous owner with no problems. I know of several with the P11 that have had similar luck with them. The smaller versions seem to have more complaints but that also seems to be the case with many of the smaller calibers.
